I also have the higest tech in the guild and the goods are for the era above me .
That's not right mate, double check your guild and if you really do have the highest era in the guild, you need to contact support. Generally you get charged x amt of goods for the previous era and x amount of goods for the current era. Each cost is per person in that era in your guild. The first level is free.

IA 2 IA Goods 4 IA Goods 8 IA Goods
EMA 2 IA Goods 4 EMA Goods 8 EMA Goods
HMA 3 EMA Goods 6 HMA Goods 12 HMA Goods
LMA 4 HMA Goods 8 LMA Goods 16 LMA Goods
